Missing math functions include lgamma(). For boost::multiprecision::float128, the implementation could simply use quadmath.h. I know that I could presumably use boost::math::lgamma(), but C++11 compatibility should be desirable." Feature Requests closed Boost 1.63.0 multiprecision Boost 1.55.0 Problem fixed
